P(Y) = 5/6
Since they are independent, P(X & Y) = P(Y) * P(X)
Therefore:
1/3 = 5/6 * P(X) Change 1/3 to 2/6, then multiply both sides by 6/5
2/6 * 6/5 = P(X)
2/5 = P(X)
Written as a decimal, P(X) = .40
Answer:
175 dollars
Step-by-step explanation:
on the graph find 3 hours then go up till you reach the line
but in the table it says that 3 hours is 180 dollars
5 times 3 is 15 and 2 times 4 is 8, so:
15-8
= 7
If it depreciates by 10% every year, that means that the tractor is (100-10)=90% of its value in the previous year. Since 90%=0.9 (by moving the decimal 2 spots to the left), we multiply 50,000 by 0.9 the first year to get the second year's value, and that by 0.9, and so on. This can be shown by 50,000*(0.9)^t where t is the time in years. Plugging 7 in for t, we get 50000*(0.9)^7=Approximately 23914.85 dollars
